Synopsis:Using a threat to Steve's life to ensnare Wonder Woman, Nazi agent Fausta Grables discovers that Diana Prince is Wonder Woman. Grables subsequently steals into Diana's apartment and finds the Wonder Woman outfit. She then begins to masquerade as Wonder Woman.

Fausta's first order of business is to hold a public competition in which she challenges other women to physically best her. Diana, no doubt eager to control the potential public relations damage done to her Wonder Woman identity by a Nazi, finds another masked outfit to wear and then answers Fausta's open call to a public wrestling match. Victory will prove to an onlooking public which of the two is actually Wonder Woman.

Unfortuantely, Fausta is able to tie up Wonder Woman with the golden lasso, stripping Diana of all her powers. Steve and Etta, having been previously alerted to the "switcheroo" are able to arrive in the nick of time to save the real Wonder Woman and right Fausta's wrongs.
